目前，根据数值模拟计算，研究溶解气驱油藏水平井向井流动态关系时，都是沿用Ｖｏｇｅｌ研究方法即制作一定采出程度下水平井ＩＰＲ曲线，然后无因次化得到无因次ＩＰＲ曲线。经研究发现溶解气驱油藏动态受生产过程的影响较大，即用不同的流压生产，当达到相同的采出程度时，油藏平均压力并不相等。故前人用数模制作无因次ＩＰＲ曲线的方法存在较大的局限性，对此提出了用数模研究溶解气驱油藏水平井无因次ＩＰＲ曲线时，应先制作油藏平均压力为定值时的ＩＰＲ曲线，然后再无因次化的新方法。按此方法对一系列溶解气驱油藏模型进行了三维流动模拟计算，总结出了无因次ＩＰＲ曲线的曲度随油藏平均压力变化的规律，提出了描述溶解气驱油藏水平井无因次ＩＰＲ曲线的新的统一方程。
At present, according to the numerical simulation and calculation, when studying the dynamic relationship of horizontal well-flow in dissolved gas-flooding reservoirs, Vogel research method is used to make IPR curves of horizontal wells with a certain degree of production recovery, and then a dimensionless IPR curve is obtained without dimensioning. The study found that dissolved gas drive reservoir dynamics by the impact of the production process is larger, that is, with different flow pressure production, when the same level of recovery, the average reservoir pressure is not equal. Therefore, predecessors’ use of digital-to-analog (IPM) curves has great limitations. Therefore, when using numerical modeling to study the dimensionless IPR curves of horizontal wells in gas-flooding reservoirs, the average pressure of reservoirs should be made IPR curve for the set value, and then no new method of dimensioning. According to this method, a series of dissolved gas drive reservoir models were simulated by three-dimensional flow, and the law of curvature of dimensionless IPR curves with reservoir average pressure was summed up. Due to the new uniform equation of the IPR curve.
